Maxim chips are not supported by NLBA reset licence and for the moment remote reset is also not possible.

You can't. You need specialized MAXIM tools software which is very expensive.

Each chip is programmed differently depeding on pack maker.

FCC can be increased maximum +300-500mah per cycle dependind on firmware. In your case FCC is very low 199mah so you will need minimum 10 cycles or more to calibrate.

But some firmwares are programmed not to increase FCC but only to decrease it, so no matter how many times you cycle the battery FCC will never increase.

 

 

If this specific battery is very important to you, you can replace the cells and send it to my workshop and i will reprogram the chip for free.
